Tight close-up portrait of a solitary woman's head, the clear astronaut helmet visor completely overflowing with vibrant, luminous poppies and cosmos flowers, the woman's eyes barely visible behind the bloom. Environment is a subtly blurred deep space nebula background. Hyperdetailed Octane render, cinematic volumetric chiaroscuro, subtle subsurface scattering, warm vibrant golden hour light illuminating the petals, ethereal surrealism, extreme shallow depth of field, 85mm lens.
